( Third Revisiba )

0. FOREWORD

0.1 This Indian Standard ( Third Revision ) was adopted *by the Rurcau of Indian Standards on 8 June 1987, after the draft linalizcd by the Wool and Wool Products Sectional Comniittee had been approved by the Textile Division Council.

0.2 The present revision of the standard has been taken up in the light of the experience gained since its revision in 1973.

0.3 In the present revision, the following major changes have been made:

a) b)

c)

d)

Requirement for mothproofing has been modified; Requirement for wool content percent has been introduced;

For breaking strength test, the ‘Revelled Strip’ test method has been Fpecified; For colour fastness to washing requirement, the staining of the adjacent fabric and for colour fastness to drycleaning require- ment the staining of the solvent have been introduced; and

Number of objectionable flaws have been modified. e)

0.4 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard prescribes the constructional particulars and other requirements cf flannel, hospital, grey.

*Rules for rounding off numerical values ( rrvisc.l).

3

X3:674- 1987

1.2 This standard does not specify the indeterminable characteristics like general appearance, feel, finish and shade of cloth ( see also 4 ).

2. TERMINOLOGY

2.0 For the purpose of this standard, the following definitions along with those given in IS : 11206-1984’ shall apply.

2.1 Virgin Wool - Pure and new wool. It means wool that has not been processed or used before and is thus distinctly different from repro- cessed or reused wool.

3. MANIJFACTURE

3.1 Yarn used in the manufacture of the cloth &all be spun from virgin wool in the woollen system. Polyamide or polyester fibres may be used in the admixture to indigenous wool to the extent of 10 to 1.5 percent, if agreed to between the buyer and the seller.

3.2 The particulars regarding the grade of wool, count of yarn, weave and finish for the manufacture of cloth are given in Table 1.

NOTE - Polyamide or polyester fibres dyed to the requisite shade may be used in admixture to indigenous wool fibres to the extent of 10 to 15 percent, if agreed to between the buyer and the seller.

*For determination of fineness grades of wool, a reference may be made to IS : 5910-1977 Fineriess grades of wool (first reviiion ).

*Glossary of textile terms-wool and other animal fibres, their processing and products.

Is : 674 - 1987

3.3 Cloth - The cloth shall te clean, scoured and free from grease, soap filli]:g or any other admixture which migl:t give fictitious weight, Lub- stance or firmness.

3.3.1 The cloth shall be uniformly woven with firm selvedges.

3.3.2 In GISF: the cloth is to be mothproofed, the same shall be rendered mothproof by suitable mothproofing chemicals which will not have any toxic effect on human body and the manufacturer should declare by which chemical the mothproofing has been done and mini- 1 mum residual percentage of mothproofing chemical in the fabric, and the suitable mrthod of test for determining the came.

NOW - The active constituents of some of the commonly used mothproofing chemicals are as fol!ows: a) Chloro-2-chloromethll sulphonamide diphenyl ether derivatives ( CCSD ), b) Halogenated diphenyl urea derivative, and c) 2-trifluromethyl-4-( 2, 4, Strichlorophenoxy )-5, 7-dichlorobenzimidazol.

3.3.3 The cloth, when visually examined against light and on a surface, sh&!l not have more than 12 objectionable flaws in a full length piece. However, in 25 percent of the pieces in the lot, up to a maximum of 16 objectionable flaws per piece may be permitted. The objectionable flaws shall be those which strike immediately the eyes of the person examining the cloth and shall be deemed to include:

a) missing ends and picks; b) floats; c) cuts and holes; d) stains; e) weft bars and warp section marks; f) big slubs, knots and specks; g) prominently noticeable thick and thin places; and h) dyeing defects ( streaks, patches ).

3.3.3.1 All objectionable flaws shall be marked by means of a thread of a contrasting shade sewn in the selvedge opposite the flaw. An allowance of 10 cm shall be given for each faw up to 12 flaFs in the piece. However, in case of pieces having flaws exceeding 12 and up to 16, an allowance of 25 cm for each such flaw shall be given.

3.3.3.2 A referenee may be made to IS : 412%1987* for details of these defects.
